Regenerative Braking May Be Making Teslas More Prone to Aquaplaning

This is absolutely the case. You have to disable regenerative braking in the winter snow as well.

  Yes but… > Tesla removed the option to adjust how intense regenerative braking is from more recent cars, which makes them brake whenever the driver is not accelerating > That is probably why Volkswagen decided to have coasting as the standard setup in the ID.4. Taking the right foot off the accelerator pedal will not trigger any decrease in speed. On the contrary: the vehicle will just sail, which is more efficient than trying to recover energy. Tesla removed the option to adjust how intense regenerative braking is from more recent cars, which makes them brake whenever the driver is not accelerating It should at least warn drivers about that. Otherwise, more people will learn the dangers of one-pedal driving after crashing their EVs

I am stunned that Tesla would decide that taking your foot off the "gas" should immediately cause braking. Feathering the throttle is the correct action when hydroplaning (aquaplaning) starts because you want to slow down just a bit to regain traction without throwing off the balance of the vehicle. Braking shifts the vehicle weight forward, which is why barking is the absolute wrong thing to do in a hydroplaning (aquaplaning) scenario.

Some brands like Subaru with their plug in crosstrek get it right. Mimic ICE coasting. Like the article mentions with puddles, There’s plenty of situations where braking is either not desired or is actually dangerous. One foot driving should not be default or possibly not even an option.
